Amarin Highlights Key Data Providing Mechanistic Insights into Eicosapentaenoic Acid (EPA) at ACC.24

DUBLIN, Ireland and BRIDGEWATER, N.J., April 08, 2024 (GLOBE NEWSWIRE) -- Amarin Corporation plc (NASDAQ:AMRN) today highlighted three data presentations at ACC.24 showcasing the mechanistic activity of Eicosapentaenoic acid (EPA), including the potential effects of EPA on endothelial cell dysfunction and on oxidation of samples enriched with Lp(a).

”The data presented at ACC.24 provide new evidence surrounding the mechanism of action for VASCEPA/VAZKEPA, including the effect of the compound in combination with high-intensity statin on endothelial cell function during inflammation and the compound’s effect on Lp(a) levels,” said R. Preston Mason, Ph.D., Brigham and Women’s Hospital. “These learnings further advance understanding of how EPA and VASCEPA/VAZKEPA work to reduce cardiovascular events in at-risk patients.”

The studies and their key findings are outlined below:

Eicosapentaenoic acid (EPA) and a High Intensity Statin Enhanced Expression of Proteins for Detoxification of Reactive Oxygen Species during Angiotensin II Challenge in Endothelial Cells

This analysis measured the separate and combined effects of EPA and rosuvastatin on expression of proteins involved in detoxification in vascular endothelial cells under inflammatory conditions with angiotensin II  (Ang II).

The combination of EPA and rosuvastatin favorably modulated the expression of proteins related to oxidative stress and detoxification under disease-like conditions. These findings indicate that the net benefits of a high intensity statin and EPA, compared to statin alone, on expression of detoxification proteins during inflammation may contribute to reduced atherothrombotic risk in outcome trials.

Eicosapentaenoic Acid (EPA) and Rosuvastatin Modulate Expression of Endothelial Proteins that Regulate Function and Platelet Activity during Angiotensin II Stimulation 

In this analysis, investigators compared the separate and combined effects of EPA and rosuvastatin on expression of proteins that regulate platelet signaling and nitric oxide (NO) levels in human umbilical vein endothelial cells (HUVECs) subjected to angiotensin II (Ang II) stimulus.

The combination of EPA and rosuvastatin favorably modulated proteins involved in platelet degranulation and NO bioavailability in HUVECs under inflammatory conditions to a greater extent than their separate treatments. The beneficial effects of a high intensity statin and EPA on endothelial dysfunction may contribute to reduced atherothrombotic risk in outcome trials.

Eicosapentaenoic Acid (EPA) Inhibits Lipoprotein(a) [Lp(a)] Oxidation due to Scavenging Mechanisms In Vitro

Elevated Lp(a) levels are an independent and causal risk factor for cardiovascular (CV) disease with limited treatments available. Oxidized Lp(a) stimulates foam cell formation, endothelial dysfunction, and inflammation. ​

In this analysis, investigators tested EPA effects on oxidation of samples enriched with Lp(a) compared to the fully saturated eicosaenoic acid (EA; 20:0) and Trolox, a water-soluble analog of Vitamin E.

Investigators found that EPA inhibited oxidation of Lp(a) enriched plasma in a time-dependent fashion consistent with a free radical scavenging mechanism. The potent antioxidant actions of EPA may contribute to reduced CV events in REDUCE-IT, including among those subjects with elevated Lp(a).

About REDUCE-IT^®
REDUCE-IT was a global cardiovascular outcomes study designed to evaluate the effect of VASCEPA in adult patients with LDL-C controlled to between 41-100 mg/dL (median baseline 75 mg/dL) by statin therapy and various cardiovascular risk factors including persistent elevated triglycerides between 135-499 mg/dL (median baseline 216 mg/dL) and either established cardiovascular disease (secondary prevention cohort) or diabetes mellitus and at least one other cardiovascular risk factor (primary prevention cohort).

REDUCE-IT, conducted over seven years and completed in 2018, followed 8,179 patients at over 400 clinical sites in 11 countries with the largest number of sites located within the United States. REDUCE-IT was conducted based on a special protocol assessment agreement with FDA. The design of the REDUCE-IT study was published in March 2017 in Clinical Cardiology.¹ The primary results of REDUCE-IT were published in The New England Journal of Medicine in November 2018.² The total events results of REDUCE-IT were published in the Journal of the American College of Cardiology in March 2019.³ These and other publications can be found in the R&D section on the company’s website at www.amarincorp.com.

 About Cardiovascular Risk 
Cardiovascular disease is the number one cause of death in the world. In the United States alone, cardiovascular disease results in 859,000 deaths per year.⁴ And the number of deaths in the United States attributed to cardiovascular disease continues to rise. In addition, in the United States there are 605,000 new and 200,000 recurrent heart attacks per year (approximately 1 every 40 seconds). Stroke rates are 795,000 per year (approximately 1 every 40 seconds), accounting for 1 of every 19 U.S. deaths. In aggregate, in the United States alone, there are more than 2.4 million major adverse cardiovascular events per year from cardiovascular disease or, on average, 1 every 13 seconds. 

Controlling bad cholesterol, also known as LDL-C, is one way to reduce a patient’s risk for cardiovascular events, such as heart attack, stroke or death. However, even with the achievement of target LDL-C levels, millions of patients still have significant and persistent risk of cardiovascular events, especially those patients with elevated triglycerides. Statin therapy has been shown to control LDL-C, thereby reducing the risk of cardiovascular events by 25-35%.⁵ Significant cardiovascular risk remains after statin therapy. People with elevated triglycerides have 35% more cardiovascular events compared to people with normal (in range) triglycerides taking statins.^6,7,8

About VASCEPA®/VAZKEPA® (icosapent ethyl) Capsules   
VASCEPA (icosapent ethyl) capsules are the first prescription treatment approved by the U.S. Food and Drug Administration (FDA) comprised solely of the active ingredient, icosapent ethyl (IPE), a unique form of eicosapentaenoic acid. VASCEPA was launched in the United States in January 2020 as the first drug approved by the U.S. FDA for treatment of the studied high-risk patients with persistent cardiovascular risk despite being on statin therapy. VASCEPA was initially launched in the United States in 2013 based on the drug’s initial FDA approved indication for use as an adjunct therapy to diet to reduce triglyceride levels in adult patients with severe (≥500 mg/dL) hypertriglyceridemia. Since launch, VASCEPA has been prescribed more than twenty million times. VASCEPA is covered by most major medical insurance plans. In addition to the United States, VASCEPA is approved and sold in Canada, China, Lebanon and the United Arab Emirates. In Europe, in March 2021 marketing authorization was granted to icosapent ethyl in the European Union for the reduction of risk of cardiovascular events in patients at high cardiovascular risk, under the brand name VAZKEPA. In April 2021 marketing authorization for VAZKEPA (icosapent ethyl) was granted in Great Britain (applying to England, Scotland and Wales). VAZKEPA (icosapent ethyl) is currently approved and sold in Europe in Sweden, Denmark, Finland, Austria, the UK, Spain and the Netherlands.
